LG Washing Machine Error Code PE: Water level (pressure) sensor error
Applies to LG washing machines that show PE on the display.
The sensor that measures water level is misreading, so the washer cannot tell how full it is. Try a power reset first.
What this code means
The pressure sensor reads water level through a small air hose to the tub. If its signal is missing or implausible, the washer cannot judge how much water it holds and stops.
The manufacturer's checks, in order
- Power the machine off at the outlet for a few minutes, then restart and run a cycle.
- Make sure the machine has not been overfilled beyond its rated load, which can confuse the level readings.
If PE returns after a reset, the pressure sensor or its air hose needs a technician.
